Every mortgage starts with one question: what will it cost each month? The calculators in this group answer it precisely — taking your loan amount, rate and term and returning the principal-and-interest payment, the full amortization schedule, and the way each payment shifts from mostly interest to mostly principal over time.
Use them to compare loan terms, fold in property taxes, insurance and PMI for a true PITI figure, or test how biweekly and extra payments shorten the loan. Each tool shows a complete schedule and a printable report, so you can see exactly where your money goes.
Payment & Amortization calculators — frequently asked
How is a mortgage payment calculated?
Your principal-and-interest payment comes from three inputs — loan amount, interest rate and term — run through the standard amortization formula. Add property taxes, homeowners insurance and any PMI to reach the full monthly PITI. The calculators above do both, plus the complete schedule.
What is amortization?
Amortization is how a loan is paid off through level payments where each one covers the interest due first and reduces the principal with the rest.
Early payments are mostly interest and later ones mostly principal, which is why the balance falls slowly at the start.
How can I lower my monthly mortgage payment?
A longer term, a lower rate, a larger down payment (which cuts the loan and drops PMI at 20% equity), or removing PMI once you qualify all lower it.
Extra principal payments don’t reduce the required payment but shorten the loan and cut total interest.
Which calculator should I start with?
Start with the Mortgage Calculator for your full monthly payment, then the Amortization Calculator to see the payment-by-payment schedule, and the extra-payment or biweekly tools to test paying the loan off faster.
